PROPULSION OF SHIPS.

SPECIFICAEION forming part of Letters Patent No. 334,580, dated January 19. 1886.

Application filed September 19, 1885, Serial No. 177,598.

To all whom it may concern:

Be it known that I, FRANZ GiRElN, a subject of the Queen of Great Britain, residing at Burly-Jacky, near Sheet-of-Bark, in the county of Bathurst, and British Colony of New South Wales, farmer, have invented new and useful Improvements in the Propulsion of Ships, of which the following is a specification.

My invention has been devised so that the wave motion or power given forth bythe undulations of .the waves may be utilized for the propulsion of ships of every description.

My improvements in the propulsion of ships consists in dividing or separating the ship transversely into two parts, which parts are connected by a cylinder sufficiently rigid to hold the two parts together and in line, and

. which extends throughout, or partly through out, the length of the ship at, on, or about the center line of gravity. One part of this cylinder is rigidly attached to its bearings in one part of the ship, while in the other part it may roll or revolve in the bearings.

In that part of the Vessel in which the cylinder is loose in its journals a cross-head is attached to the cylinder end,from which rods are connected to air-pumps or other compressing machinery, by which air or other gases may be pumped into a reservoir, from which it may be supplied to engines to work paddle-wheels, screws, or other propelling mechanism.

Referring to my drawings herewith, Figure l shows the hull of a ship divided transversely into two parts, and provided with a connecting-cylinder according to my invention, and Fig. 2 is a section of the same. on line c a in Fig. 1.

A is the fore part of the hull; A2, the aft part. B is the cylinder. O is a cross-head or walkingbeam, and D air-pumps. B and B2 are bearings, or standards, or posts extending vertically upward from the bottom ofthe respective sections, and supporting the cylinder at its respective ends, and also at or near the point of juncture of the two sections of the hull; and B3 represent stays for (No model.)

said bearings. C are glands, and D represent pump-rods connected to the cross-head. The cylinder B, which is sufficiently rigid to keep the two parts A and A2 fairly in line, is rigidly attached to the bearings B', but revolves in bearings B2 in the aft part of the hull.

As the waves give the ship an undulating motion, the cylinder B revolves with the fore part, A', and moves in its bearings B2 in the aft section, thus moving the ends of the crosshead C and working the pistons of the air-pumps D, thereby pumping and cornpressing air intoa reservoir,(not shown,)frorn which said air may be drawn to work the engines of the vessel.

I may form the hull in more than two transverse sections instead of one, and sometimes the parts of the vessel may be bolted or otherwisefastened together in such a manner that the distinctive sidewise motions of each part will not be interfered with, as by bolts whose heads travel in circular slots. The ship will also be strengthened in such of its parts as my method of constructionwill render necessary.

Having thus particularly described and ascertained the nature of the said invention, and the manner in which the same is to be performed, I would have it understood that I do not confine myself to the precise manner in which the same may be carried into effect so long as the nature thereof be retained; but,

What I believe to be novel, and therefore claim as my improvement in the propulsion A ship having a hull formed in transverse sections, standards or posts extending upwardly from the respective sections at or near the point of juncture and near the fore and aft ends, respectively, of the hull, a cylinder extending longitudinally along the hull, so as to connect the respective sections, and having rigid bearing within the standards or posts connected with the fore part of the hull, and loose bearing within the standards or posts in the aft part of the hull, a crosshead or walking-beam connected to the rear ings and operate the cross-head and pumpend of said cylinder, and air-pumps having rods, substantially as and for the purpose set their piston-rods connected to the said Crossforth.
